Specific embodiment
Present pre-ferred embodiments are given below, in order to explain the technical scheme of the invention in detail.
Power battery module assembly method of the present invention the following steps are included:
Step 1, battery code scanning test, battery, will be on pallet carryings to caching pipeline by being manually placed into pallet;It is mechanical
Hand grabs battery out of pallet and carries out barcode scanning, rear to carry out OCV(Open Circuit Voltage, open-circuit voltage) test, it will be electric
Core is put into transfer station and carries out barcode scanning;Unqualified battery core is transferred to unqualified magazine after the completion of barcode scanning test, and qualified product battery core turns
Discharging docking mechanism is moved on to, front and back sides classify;Battery discharges after barcode scanning on the conveyor line;Battery core discharging two dischargings of setting
Mouthful, battery core front and back sides classify, and improve the complete machine speed of service;Unqualified grading manipulator has rotating mechanism, battery supplied materials
When direction is reversed, manipulator rotates 180 °, and battery core is adjusted to unified direction automatically.With test probe on manipulator, use
It is positive and negative and open-circuit voltage (OCV) in the polarity of detection battery core, raising accuracy in this way.
Heat insulation foam and partition gummed paper are pasted integral, heat insulation foam surrounding four glue of patch by step 2, partition feeding.If
Back-up is the stations such as feeding, positioning, rubberizing, blanking.Whole folded material is manually put into feeding cache location, manipulator automatically grabs
Material is put on working rotary table.
Step 3, end plate feeding, in the whole frame end plate feeding of upper discharge position.Feeding manipulator is drawn end plate from material frame and is transferred to
Transfer platform is positioned, grabs two blocks of materials every time;The end plate of side overturns 180 ° on transfer platform;One after the completion of end plate overturning
It rises and is transferred to locating platform, positioning mechanism carries out Laser Jet after positioning to end plate;Discharging pair is transferred to after the completion of end plate stamp
Connect station.
Step 4, battery core stack, battery core and end plate feeding robot from battery core material frame and end plate workbench crawl battery core and
End plate is put into stacking station, grabs a material every time;Partition feeding robot crawl endplate is put into stacking station.Two machines
Device people works alternatively, and is calculated with six battery core mould groups, produces a set product per minute.
It stacks robot crawl battery core/end plate/partition to be stacked to mould group prepackage platform, stacks band Check up polarity on fixture
And end plate mistake proofing detection, guarantee that the assembly of mould group is correct.
Stacker uses two station turnplate formula structures, another station docking robot goes out while a station stacks
Material.Side block side is stacked, the parts surfaces such as rib coat insulating materials before battery core, prevent plowing from battery core or the phenomenon of short circuit occur.
Step 5, robot transfer, battery core mould group stack assembled portion and use three six-joint robots in total, and specially the
One six-joint robot, the second six-joint robot, third six-joint robot.First six-joint robot is for grabbing partition;Two or six
Axis robot is for grabbing battery core and end plate;Third six-joint robot stacks mould group for grabbing.First six-joint robot uses
Partition is taken, is furnished with vacuum meter, real-time monitoring grabs sucker negative pressure when material, does not catch the suction of material alarm sucker.Two or six
Axis robot is compatible with two kinds of materials of battery core and end plate, works at the same time crawl material using sucker and clamping jaw, dual grasp mode is same
When work, prevent crawl material unstable or inadvertently fall off.It grabs sucker and is furnished with vacuum meter, real-time monitoring grabs suction when material
Disk negative pressure does not catch material alarm.Material is detected equipped with inductor inside clip claw mechanism.Third six-joint robot is compatible with side plate
With two kinds of materials of mould group.Side plate clamping jaw is for grabbing side plate.Mould group embraces folder and mould group side plate simultaneously clamps on mould group and prevents mould group
Shaking is fallen.Mould group clamping jaw is furnished with pressure reducing valve, for adjusting clamping force when crawl mould group.Inductor is housed inside clip claw mechanism
For detecting material.
Step 6 holds plate-side plate welding, whole to turn after dress plate-side plate welding fixture is connected to die set using duplexing bit architecture
Move to positioning dress side plate station;Fixture is centered about mould group, and cell polar ear is downward, hold-down mechanism clamping die group, with tab face
Positioning compression is carried out as benchmark;Hold-down mechanism compresses mould group length direction, while monitoring mould group length and pressure, and
Upload data;Side plate is installed in mould group by side plate installing mechanism, side plate and end plate in the state of compression, integral clamp turn
Move on to welding post;Entire mould group is welded under impaction state, and end plate and side plate are according to unilateral welding four of technique requirement
Weld seam.
Mould group is transported to Laser Welding station, jacking positioning by step 7, connection sheet welding, pipeline, and equipment carries out mould group
It compresses, robot band vision carries out vision positioning to mould group, surveys high, laser welding;Mould group welding dedusting simultaneously removes welding slag;It is defeated
Mould group is transported to weldering room quality testing station by line sending, and jacking positioning carries out weld seam to mould group and takes pictures, underproof to be directly transferred to
Unqualified caching waits manual operation.
Bottom hot plate is put on glue spreader by step 8, offline gluing, operator, presses glue spreader after ACK button
Automatic glue application, buzzer and indicator light work, remind operator to take out glue-coated heating plate after the completion of gluing.
Mould group is transported to mould group detection station by step 9, the test of mould group, pipeline, and jacking positioning manually carries out mould group
Insulation test, IR(insulation impedance) test, the test of connecting line on off test, temperature sensor scheme, after the completion of testing
Data are uploaded to MES system, and (Manufacturing Execution System, i.e. manufacturing enterprise's production process execute system
System).The rejected product of test is manually transferred out of pipeline.Insulation test: pressure resistance survey of insulating is carried out between measurement complete machine and shell
Examination.IR&OCV test: mould group entirety IR&OCV test.Route connects test: the circuit on-off that confluence is discharged to p-wire plug is surveyed
Examination.Temperature sensor scheme test: temperature sensor both threads carry out short-circuit test with shell respectively.MES system is entire raw
The cental system of producing line, MES system data include creation data and product data, these key datas both can be tieed up manually
Shield or tool batch import, and can also pass through the integrated automatic transmission of MES completely.
Step 10, mould group is offline, and manual operation servomechanism is offline by the mould group transfer on pipeline.
In conclusion the present invention mainly adopts in an automated fashion, improve efficiency, reduces cost.
